Grace Design M-902 (c. 2009)
Documentation on the Grace Design M-902 is thin, and the model is absent from most period catalogs. What survives comes mostly from one professional review of its successor variant, the m902B. Pro-Audio-Review (June 2009, p.20) called the m902B a reference headphone amplifier with a list price of $1,850. It noted that Michael Grace came from a high-end consumer audio background that put more weight on build quality than most pro-audio manufacturers did. The review praised the unit's DA conversion and build quality, and put its street price around $1,750.
The m902B appears to have been a monitor controller and headphone amplifier for studio professionals. It had reference 24/192 DACs and analog circuitry positioned as a transparent link between a mix and monitors. Beyond the review, little else is recorded. No production run dates, no detailed specifications and no service documentation have turned up in the archive.
